Detailed Description

Integrate an initial value problem using 2nd order Runge-Kutta method.

This is a concrete sub-class of vtkInitialValueProblemSolver. It uses a 2nd order Runge-Kutta method to obtain the values of a set of functions at the next time step.

virtual const char* vtkRungeKutta2::GetClassName (  )  [virtual]

Reimplemented from vtkInitialValueProblemSolver.

static int vtkRungeKutta2::IsTypeOf ( const char *  name  )  [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkInitialValueProblemSolver.

virtual int vtkRungeKutta2::IsA ( const char *  name  )  [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkInitialValueProblemSolver.

static vtkRungeKutta2* vtkRungeKutta2::SafeDownCast ( vtkObject o  )  [static]

Reimplemented from vtkInitialValueProblemSolver.

static vtkRungeKutta2* vtkRungeKutta2::New (  )  [static]

Construct a vtkRungeKutta2 with no initial FunctionSet.

Reimplemented from vtkObject.

virtual int vtkRungeKutta2::ComputeNextStep ( double *  xprev,
double *  xnext,
double  t,
double &  delT,
double  maxError,
double &  error 
) [inline, virtual]

Given initial values, xprev , initial time, t and a requested time interval, delT calculate values of x at t+delT (xnext). delTActual is always equal to delT. Since this class can not provide an estimate for the error error is set to 0. maxStep, minStep and maxError are unused. This method returns an error code representing the nature of the failure: OutOfDomain = 1, NotInitialized = 2, UnexpectedValue = 3
